Myositis ossificans (MO) is a disease whose main feature is the formation of heterotopic bone involving muscle or any other soft tissue. Pathogenesis is not all clear, but trauma is universally recognized as a trigger event. Myositis ossificans can be divided into 2 classifications: MO progressiva and MO traumatica. The authors present a case of a 64-year-old man who was diagnosed with MOT of the left medial pterygoid muscle. The patient had a long clinical history of signs and symptoms of temporomandibular articulation related to previous conditions, and no major traumatic events were reported, apparently related to MOT.

UI	MeSH Term	Description	Entries
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D011626	Pterygoid Muscles	Two of the masticatory muscles: the internal, or medial, pterygoid muscle and external, or lateral, pterygoid muscle. Action of the former is closing the jaws and that of the latter is opening the jaws, protruding the mandible, and moving the mandible from side to side.

D001706	Biopsy	Removal and pathologic examination of specimens from the living body.	Biopsies
D049268	Positron-Emission Tomography	An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell metabolism. It has been useful in study of soft tissues such as CANCER; CARDIOVASCULAR SYSTEM; and brain. SINGLE-PHOTON EMISSION-COMPUTED TOMOGRAPHY is closely related to positron emission tomography, but uses isotopes with longer half-lives and resolution is lower.
